Switch Placement Help

Earlier today I posted in the What have you done today thread about some switches I received. So today I go out to the truck to install them. The only problem is when I take off the panel the clearance behind the panel is almost zero!! I was looking to install them inthe panel below the HVAC/Radio panel. The bluetooth control module is mounted in that location ad takes up almost the entire area.
Which brings me to my question. Where should I mount them? They are about 2 1/2 inches deep. I want them with in a comfortable arms reach.
